The granite loses 1.53 × 10⁸ J of heat.
The formula for the heat (<em>q</em>) transferred is
<em>q = mC</em>Δ<em>T
</em>
I shall assume that the specific heat capacity of granite is 0.790 J·°C⁻¹g⁻¹.
<em>m</em> = 3.580 × 10⁶ g; Δ<em>T</em> = <em>T</em>_f – <em>T</em>_i = -12.9 °C - 41.2 °C = -54.1 °C
∴ <em>q</em> = 3.580 × 10⁶ g × 0.790 J·°C⁻¹g⁻¹ × (-54.1 °C) = -1.53 × 10⁸ J
The granite block loses 1.53 × 10⁸ J.
Answer is: <span>Mutations sometimes improve the chances of survival for a plant.
</span>Mutations are very important because they change <span>variability in populations and in that way enable evolutionary change.
</span>There are three types of mutations:
1) good or advantageous mutations - <span> improve the chances of survival for a plant.
2) </span>bad or deleterious - decrease the chances of survival for a plant.
3) neutral - not affect he chances of survival for a plant.
Why do they act like humans
B because it has a lower activation energy
